What do I need to re-emerge to fix this problem? I'm getting this on mysql-administrator and smbc-1.2.1.

$ mysql-administrator
*** glibc detected *** free(): invalid pointer: 0x081c80f0 ***
/usr/bin/mysql-administrator: line 9:  4127 Aborted                 $MYPATH/mysql-administrator-bin

Thanks.

The error you are seeing shows that there's a bug in mysql-administrator.

You can tell glibc to ignore the error and try to resume. Try this:

Code: Select all

MALLOC_CHECK_=1 mysql-administrator

or if you're using tcsh:

setenv MALLOC_CHECK_ 1
mysql-administrator

I got the same problem with gtksee and wmmisc after an glibc update. When i downgraded to glibc-20040808 the problem dissapeared, so the logical conclusion would be that something is wrong with glibc, or what?

paulbiz · Post by **paulbiz** » Sat Apr 30, 2005 6:23 am

It is a feature of glibc to detect corruption before it happens. It is a bug in the program that caused it. Invalid pointer, free() of memory that's already gone, etc.

You can control it on a per-run basis by setting the MALLOC_CHECK_ environment variable. If you explicitly set this variable it performs even more strict tests than normal.

0 -- Do not generate an error message, and do not kill the program
1 -- Generate an error message, but do not kill the program
2 -- Do not generate an error message, but kill the program
3 -- Generate an error message and kill the program

There is a "nomalloccheck" USE flag for glibc. Perhaps setting that will turn off this feature? I haven't tried it (glibc compile is so fast!)

yep, the nomalloccheck USE flag disables these warnings. thanks for the info about MALLOC_CHECK_. i'm bookmarking this.

"man malloc" and check the NOTES section at the bottom

I've tried firefox 1.0.4 installer, alpha 1 installer, alpha 2 installer, and latest trunk installer with no success. I tried recompiling glibc with the "nomalloccheck" use flag and nothing changed. I tried to run the firefox installer with setting MALLOC_CHECK_=1 to avoid program termination, but this also failed as one can see below.

Code: Select all

I was told that this error might also relate to the cflags used for glibc. I use the following cflags.

Code: Select all

CFLAGS="-O3 -march=pentium4 -mtune=pentium4 -fforce-addr -momit-leaf-frame-pointer -fomit-frame-pointer -ftracer -pipe" 
CXXFLAGS="${CFLAGS} -fvisibility-inlines-hidden"

BobP recommended these cflags, even though may seem optimistic they're supposed to be very stable and reliable.

Even when I try to compile and install deer park alpha 1 or 2, when I try to run it nothing loads and firefox-bin shows up in my ProccessTable. I only have success when compiling 1.0.4, which is the version I'm trying to avoid because of its overall slow performance.

Any assistance would be greatly appreciated.

Thanks,
Ray

I'm stuck with a similar problem with ipac-ng. I'm not exactly shure when the problem occured as I've done several "emerge -uDvp system" without restarting the firewall. When I try to run fetchipac -S I get

Code: Select all

a48056 ~ # fetchipac -S
*** glibc detected *** free(): invalid pointer: 0x08079428 ***
Aborted

I have already tried the MALLOC_CHECK_="1" environment variable, but it doesn't seem to help.

Code: Select all

a48056 ~ # MALLOC_CHECK_="1" fetchipac -S

From what I understood this could be related to CFLAGS and timings, so I tried recompiling ipac-ng with several other CFLAG settings but I still get the same error. Below is the output of emerge info. Does anybody have any idea how to resolve this?

Any feedback is greatly appreciated.
Alex.

Nomalloccheck was removed from 2.3.5-r1 so now it's always on by default.

frusware · Post by **frusware** » Fri Sep 02, 2005 7:07 pm

so there is no other way of suppressing the error message? Please don't tell me I have to emerge an older glibc.

chtephan · Post by **chtephan** » Fri Sep 02, 2005 7:19 pm

Suppressing the malloc check would be working around the symptoms.

Fact is that one of programs (or libraries) you are using is buggy and writes to memory it shouldn't. You could always recompile your glibc with the nomalloccheck USE flag, but the real question is how you can figure out what is poking around in your memory.

Valgrind is a tool that does that. I'm using a glibc with malloc checks for a long time now and I have seen this message, but it always went away after the bug was fixed. So simply disabling the check would be the "duck and cover" strategy.

Is it only firefox-installer or do you see this with other programs too. Finding a common denominator would ease helping the broken package. If you are a bit familiar with debugging you could also try valgrind.

I agree, I rather not suppress the error and I would like to resolve it correctly (I'm getting the error in ipac-ng, not in the firefox-installer). I'll see what valgrind can turn up, but since I'm a lazy ass java programmer who never has to deal with allocating memory, it could take a while before I track down the bug in ipac-ng.

Has anyone managed to resolve this issue yet?

frusware · Post by **frusware** » Thu Sep 15, 2005 5:35 am

As chtephan pointed out, it's not so much a problem with glibc or your compiler, but it has to do with the lib/app doing something it's not supposed to do. For the original poster jeffk a fix in mysql-administrator and smbc are required and for me, a fix in ipac-ng.

I know this topic is really old, but I've noticed this problem with some C++ programs I've written that implement the destructor and copy constructor. The trouble resides there (at least in my case).

zoltak · Post by **zoltak** » Mon May 08, 2006 6:11 am

I upgraded IPTABLES and IPACC. This fixed the issue. There was a bug in IPACC when referencing something in the new version of IPTABLES. Maybe its a bug in your code?

edit: typo!
